Large file support committed

[Pavel Roskin <proski gnu org>]

Hello!

I've committed a patch that enables large file support in MC. Autoconf
2.50 should be used to enable this support, since Autoconf 2.13 lacks
AC_SYS_LARGEFILE.

The large file support should be enabled explicitly by giving
--enable-largefile to configure. This support has not been tested much, so
please consider this feature experimental for the time being, especially
on big-endian machines (PowerPC, Sparc), where it hasn't been tested at
all.

ChangeLog
        * configure.in: For Autoconf 2.50+, use AC_SYS_LARGEFILE.
        It should be enabled explicitly by giving `--enable-largefile'
        to configure.
        * INSTALL: Document it.

Pavel Roskin
